NPT Tap Drill Chart Explained What is an NPT Tap Drill Chart?Īn NPT Tap Drill Chart is a reference tool that provides guidance on the appropriate tap drill sizes for specific NPT thread sizes and pitches. Top 12 Best Drill Bits for Metal Drilling.Top 15 Best Drill Bits for Hardened Steel.A tap drill that is too large (or a tap that’s too small for the hole created) results in shallow internal threads and the potential for stripping. Clearance between the tap hole and the tap’s diameter reduces tap wear and the effort required. The choice of the right tap drill size is critical for several reasons. The hole created by the tap drill serves as a guide for the tap, ensuring that the threads are cut accurately and to the proper depth.
A tap drill is a specific-sized drill bit used to create a hole in a workpiece before tapping threads into it. The Significance of Tap Drills What is a Tap Drill?īefore we dive deeper into the NPT Tap Drill Chart, it’s crucial to understand what a tap drill is and why it matters. Pipe threads used in hydraulic circuits can be divided into two types: Jointing threads are pipe threads for joints made pressure tight by sealing on the threads and are taper external and parallel or taper internal threads. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound. Carbon Steel NPT Pipe Taps are for cleaning threads in all materials and making new threads in soft materials.
Understanding NPT TapsĪlso called ‘pipe taps’, National Pipe Taper (NPT) taps are appropriate for threading a wide variety of materials both ferrous and non-ferrous. Before start lets understanding about the NPT tap drill. This size chart is a must-have for anyone involved in metal drill, machining, or fabrication. Here you will find NPT Tap Drill Size that is the perfect addition to any CNC shop & garage toolbox. This versatile & practical tool provides an invaluable resource for professionals and hobbyists alike, offering comprehensive information on tap drill sizes, decimal equivalents, and fractional metric measurements.
